DIS QuakeBase

What is QuakeBase?QuakeBase is an isolated platform that uses double concave sliders to protect from earthquake damage. It’s designed to be an economical solution for low to medium seismic zones.

How does QuakeBase Function?QuakeBase works on the same principals as a simple pendulum. Energy from an earthquake is dissipated through friction at the sliding interface. Movement of the system is controlled by the curvature of the sliding surfaces.

QuakeBase is modular and can be configured to suit any server or equipment layout. Adjacent modules bolt together to form a continuous system.

Ideal Candidates for QuakeBase

Mainframes

Server Racks

Optical Storage Units

Servers remain stationary duringevery day use and maintenance.

Easy installation in both newand existing data rooms.

Advantages of QuakeBaseQuakeBase reduces earthquake energy transmitted into servers by decoupling them from the ground during a seismic event. In addition, QuakeBase removes energy through internal friction.

QuakeBase’s low height allows for easy installation in both new and existing data rooms. No drilling is required for installation.

Due to the friction interface in QuakeBase, servers remain stationary during everyday use and maintenance.

Concave sliding surfaces control seismic response.

QuakeBase is sized to accommodate standard server cabinets.

Why Use An Isolated Platform?Computer servers and systems are key to business operation in todays data-dependent world.

Isolated Platforms provide protection against server downtime and equipment damage in the event of an earthquake.

More Server Uptime Protecting data centers and essential equipment against system failure with backup power and mirrored storage are common practice.

However, protection against seismic forces is also vital. Conventional earthquake protection utilizes strengthening techniques which actually increase seismic forces and accelerations. Conversely, Isolated Platforms reduce equipment forces.

Systems and equipment remain undamaged, operational and on-line. Seismic isolation has been utilized to achieve Uptime Institue’s Tier 4 rating in seismic zones.

ConfigurationsDIS’ patented IP is comprised of Multi-Directional Springs and high-load capacity rolling supports housed within an attractive steel frame. Modules are available in Standard (4ft x 4ft) and Extended (4ft x 6ft) sizes.

Individual platforms can be bolted together on all four sides, allowing for versatile layouts. (i.e., for supporting single servers or a long row of server racks.)

Platform heights range from 7 to 11 inches, depending on the required load capacity.

PerformanceDuring a seismic event the Isolated Platform decouples the system from f loor motions and absorbs seismic energy. The f loor moves beneath the IP, leaving what it supports largely unaffected. Transmitted accelerations are reduced by up to 5 times.

Standard DIS Isolated Platforms are designed for 100psf to 500psf f loor loading in moderate to high seismic regions. Custom engineered solutions are available to suit any application.

Seismic protection for applications that require acceleration reduction horizontally and vertically.

DIS 3D Isolation

The Need for 3D Isolation?Seismic isolation is typically engineered to protect against horizontal accelerations during a seismic event. In some applications, however, signif icant ver tical accelerations are present as well. DIS has developed a solution to reduce these forces.

Dynamic Isolation Systems developed a product which provides isolation from damaging accelerations in both horizontal (X, Y) and vertical (Z) directions.

The solution for isolating in both the horizontal and vertical directions came about when a major hydro-electric dam project needed to protect critical equipment from extreme vertical accelerations.

The equipment at the top of the hydro-electric dam was subjected to spectral accelerations up to 17g. These large accelerations would damage sensitive equipment following a seismic event causing dam controls to be inoperable.

DIS developed 3D isolation platforms to reduce forces and accelerations transmitted into the equipment to be within IEEE 693 High Per formance code requirements. The successful development of 3D isolation led to the client incorporating vertical isolation systems in several additional applications.

DIS’ 3D isolation systems are the most ef fective and complete solution for addressing earthquake hazards. DIS specializes in custom design, development, and manufacturing of solutions such as 3D isolation.

Raised Floor Configurations

Why Use An Isolated Floor?Risk management for computer servers and data centers is an integral par t of modern business.

Often the productivity of an entire company hinges on the reliable and continuous operation of its computer equipment.

In addition to backup power and mirrored data storage, seismic isolation is a critical piece of the risk management puzzle.

DIS Isolated Floor systems provide continuous, single-level f looring with seamless integration of conventional, raised-access f loors.

Conventional earthquake protection relies on structural strengthening techniques, which actually increase seismic forces and accelerations. DIS’ Isolated Floors reduce seismic forces. Systems and equipment remain undamaged, operational and on-line both during and after a seismic event.

Seismic isolation has been utilized to achieve Uptime Institute’s Tier 4 rating in seismic zones.

ConfigurationDIS’ patented Isolated Floor is comprised of Multi-Directional Springs and high-load capacity rolling supports in standard 4ft x 6ft modules which accommodate standard 2ft x 2ft access f loor tiles.

Modules are connected with either 2ft, 4f t or 6ft stringers and may be connected on all four sides, allowing for custom configurations.

Under f loor utilities may be organized through incorporated cable trays and remain accessible via standard access f loor tiles or placed on the f loor below the stringers.

DIS Modular Isolation System (MIS)

Why Use A Modular Isolation System?Modular data centers are a key component for business operations in today’s growing data industry. DIS’ Modular Isolation System (MIS) provides protection against server downtime and equipment damage in the event of an earthquake.

Installing backup power and having mirrored storage are common practices for protecting data centers and essential equipment.

However, the missing piece of this risk management puzzle has been the protection from seismic events. This can be provided by DIS’ Modular Isolation System.

Conventional earthquake protection utilizes strengthening techniques, which actually result in increased seismic forces. The MIS, however, reduces seismic forces. Systems and equipment remain undamaged, operational and on-line.

PerformanceDIS’ patented MIS is comprised of Multi-Directional Springs (MDS) and high load capacity rolling supports housed within an attractive steel frame. The frame matches the footprint of a standard modular data center and is only 12” (300mm) tall.

During a seismic event the ground moves beneath the MIS, leaving the data center and its equipment unaffected by the earthquake. The MIS decouples the data center from the ground and absorbs seismic energy.

Standard MIS’ are designed for 25,000 to 65,000 pound modular data centers in moderate to high seismic regions. Custom solutions are available for any application.
